Horizontal sidebar - widgets next to one another?

Hey, I am unsure if this is the right forum or if I should head over to wordpress.org. I would imagine that it's the same coding for both systems. Anyways, I have a testing page (domain listed + /test) and have a question about creating horizontal sidebars.

I have widgets at the bottom, under the index content, which was inserted as a sidebar on first line of footer.php. It loads the widgets vertically, as it is supposed to, and I don't know how to load them horizontally, so that they all can have equal amount of space to operate.

Does anyone know how to change vertical to horizontal widget loading for sidebars?
